Daily Status Report as of 232/0000Z
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed Three Sets of WF/PC-2 6909 (WF/PC-2 Cycle 6 Calibration: =
Earth Flats)
The WF/PC-2 was used to make observations of the bright earth to =
obtain streak flats which are used to construct high quality flat fields =
for the WF/PC-2 filter set. The observations were executed as scheduled, =
and no anomalies were noted.
1.2 Completed Two Sets of WF/PC-2 6346 (Snapshot Survey of the =
Ultraluminous IRAS Galaxy Sample-Part 1 High)
The WF/PC-2 was used to make snapshot survey observations of the =
ultraluminous IRAS galaxies CL-ULIR231 and CL-ULIR225. These data will =
be searched for multiple cores, which imply a merger has occurred, and =
for starburst regions. The observations were executed as scheduled, and =
no anomalies were noted.
1.3 Completed FOS/BL 6727 (A Unique Test of Astroseismology: The DBV =
GD358)
The Faint Object Spectrograph (Blue Side) was used to make rapid =
mode, ultraviolet, spectrographic observations of the white dwarf star =
V777 Her (aka, DVB GD358) to determine the pulsation indices of the =
non-radial g-mode light variations. This is part of a unique test of =
astroseismology. Knowledge of the indices provides constraints on the =
structure and evolution of the star and, possibly, on its mass and =
distance. The observations were executed as scheduled, and no anomalies =
were noted.
1.4 Completed Four Sets of WF/PC-2 6188 (WF/PC-2 Cycle 5 Calibration: =
Dark)
The WF/PC-2 was used to make internal dark calibration images. =
The observations were completed as scheduled, and no problems were =
reported.
1.5 Completed WF/PC-2 6361 (High Resolution Imaging of X-Ray Selected =
AGNs)
The WF/PC-2 was used to make high resolution observations of the =
known low red shifted x-ray active galactic nuclei (AGN) MS1322.3+2. =
These data will allow a study of the optical properties of an unbiased =
sample of AGN host galaxies. The observations were completed as =
scheduled, and no problems were reported.
1.6 Completed FOS/RD 6801 (C and N Production and Pollution Mechanism =
in Low-Metallicity)
The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of the dwarf galaxy T1345-420 to measure its =
N, O and C emission lines in its H II regions. The observations were =
completed as planned and no anomalies were reported.
1.7 Completed WF/PC-2 6905 (WF/PC-2 Cycle 6 Calibration: Internal =
Monitor)
The WF/PC-2 was used to make several internal calibrations =
observations including biases and internal flats as part of a Cycle 6 =
calibrations procedure. A variety of internal exposures are run weekly =
to verify and monitor the health of the camera. The observations were =
executed as scheduled, and no anomalies were noted.
1.8 Completed Two Sets of GHRS/2 6213 (GHRS Aperture Offsets- Cycle 5)
The High Resolution Spectrograph (Side Two) was used to make =
calibration images of the star HD141556 in order to determine the offsets =
of the instrument's focal plane apertures. The purpose of this =
calibration program is to measure the relative wavelength of offsets =
between the large science aperture and the small science aperture with =
various gratings. A wavelength calibration image was also taken. The =
observations were completed as scheduled, and no anomalies were reported.
1.9 Completed WF/PC-2 6347 (A Search for Jets in Planetary Nebulae)
The WF/PC-2 was used to make observations of the planetary nebulae =
(class PNe) PK003+02D1 in order to search for the presence of possible =
narrow jets. The current model for PNe formation indicates that jets are =
an unexpected phenomena. Yet there is a growing body of circumstantial =
evidence that suggests narrow jets are common feature in PNe. The =
observations were completed as scheduled, and no anomalies were noted.
1.10 Competed Two Sets of FOS/RD 6552 (Spectrophotometry of Inner =
Jovian Satellites)
The Faint Object Spectrograph (Red Side) was used to make =
spectrographic observations of Jupiter's inner moons, Metis and Amalthea, =
during their eastern elongation. Many things can be determined from the =
analysis of these spectra. During the first iteration of this proposal, =
the FOS binary target acquisition failed when no target object was =
located in the aperture. A status buffer message to this effect was =
generated. HSTAR 5693 was written to describe this event. Otherwise, =
the observations were executed as planned, and no further problems were =
reported.
1.11 Completed Two Sets of WF/PC-2 6359 (Core Properties of the Bulges =
of Spiral Galaxies)
The WF/PC-2 was used to make snapshot survey observations of =
spiral galaxy NGC-7013 in order to study its central bulge. The aim is =
to investigate the core properties, correlations with global galactic =
properties, and the frequency of occurrence of multiple and/or =
miscentered nuclei. The observations were completed as scheduled, and no =
anomalies were noted.
1.12 Completed WF/PC-2 5848 (The Nuclear Disk in the E4 Galaxy =
NGC-7052)
The WF/PC-2 was used to make observations of the E4 class radio =
galaxy NGC-7052 to study its nuclear disk and the kinematics of the gas =
near the nucleus. The observations were executed as scheduled, and no =
anomalies were noted.)
1.13 Completed GHRS/2 6076 (XI BOO A: Structure and Non-Thermal =
Heating)
The High Resolution Spectrograph (Side Two) was used to make high =
resolution spectrographic observations of the binary system star HD131156 =
(aka, XI Boo A and B) in order to study its structure and non-thermal =
heating. From these data an improved value for the electron density will =
be obtained. The observations were completed as planned, and no problems =
were reported.
1.14 Completed FGS 6566 (Calibrating the Mass-Luminosity Relation at =
the End of the Main Sequence)
The FGSs were used to make astrometric observations of the =
components of the low-mass, binary system, star G250-29 in order to make =
a calibrations of the mass-luminosity relation at the end of the main =
sequence. The individual stars have masses of less than 0.2 solar =
masses. The observations were completed as scheduled, and no problems =
were noted.
1.15 Completed FOS RD 6487 (Spectroscopy of the Inner Satellites of =
Uranus)
The Faint Object Spectrograph (Red Side) was used to make prism =
spectrographic observations to Uranus' inner moons, Miranda, Puck, Portia =
and Juliet. The observations were completed as planned, and no problems =
were reported.
1.16 Completed GHRS/1/2 6594 (White Dwarf Companions of Barium and CH =
Peculiar Stars)
The High Resolution Spectrograph (Sides One and Two) was used to =
attempt to make spectrographic observations of the white dwarf of the =
Barium and CH Peculiar class star HD165634-B. This will test the theory =
that abundance anomalies in this star caused by mass transfer from the =
precursor of the white dwarf. The observations were executed as =
scheduled, and no anomalies were noted.
1.17 Completed WF/PC-2 6119 (Snapshot Survey for Companions of =
Planetary Nebula Nuclei)
The WF/PC-2 was used to make snapshot survey observations of =
planetary nebula MZ2 to study its nucleus and to look for possible =
companions. The observations were executed as scheduled, and no =
anomalies were noted.
